Readiness Potential (RP)
Canonical definition
The readiness potential (RP) is the slow negative shift in electrical potential measured over motor cortex (via EEG) that begins 350–800 milliseconds before conscious awareness of intention and 800–1500 milliseconds before the executed voluntary action, demonstrating that neural preparation for action precedes conscious decision, thereby creating a temporal window during which preconscious inputs (including Mimetic signals processed within the Transmission Window) shape choice architecture before consciousness can intervene.
Explanation
Benjamin Libet’s 1983 experiments recorded RP while subjects performed spontaneous voluntary actions (such as flexing a wrist) and reported when they consciously “decided” to act. The RP (neural preparation) began hundreds of milliseconds before conscious intention, which itself preceded the muscle movement. For AIM, the claim is architectural, not metaphysical: there is a measurable lag between when the brain starts preparing an action and when consciousness becomes aware of “deciding.” Preconscious Mimetic inputs arrive and are integrated during this lag. By the time the person can ask “do I really want this?” the Decision Hub has already combined A, I, and M into a single urgency signal. Conscious veto remains possible, but awareness is late and works on an already-shaped option set. RP thus underwrites the claim that the timing barrier is structural: awareness arrives after integration because of constraints in motor preparation, not just from inattention or laziness.
